v My present invention provides an eXtremely simple and highly efficient ice-cream carton filling device and, generally stated, the invention consists of the novel construction, arrangement and combinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the Vaccompanying drawings, whereinplike characters indicates like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a side elevation showing the complete device, some parts beingbroken away;

Fig. 2 is an axial section ofthe device, the handle thereof being broken away;

Fig. 3 is ahorizontal section on theline 8-3 of Fig. 1;

Fig. 4 is a horizontal section on the line 4 4 of Fig. 1; y

Fig. is an enlarged fragmentary section on the line 5-5 of Fig. 2; and

Fig. 6 is a plan view showing a combined scraper and clamping ring adapted to be used in connection with the device.

The character A indicates a` cylindrical paper carton adapted to be filled with icecream. This carton, as shown, is of a long size capable of holding, say, one quart: of ice-cream, but the device, as will hereinafter be noted, is capable of handling shorteror half-length paper cartons adapted to contain each a pint of ice-cream. The paper carton is arranged to be placed within av cylindrical metal shell, which, to contain the long or quart size carton A, is shown'as made up of two metal cylinders 7 and 8 of the same diameter andadapted to be connected and operated as a single casing by interlocking joints, suchras Abayonet joints. rl.`liesebayo1iet joints, preferably, 4are formed by L-shaped lugs9 projected from the lower edge of the upper cylinder 7 and detachably engageable with L-shaped notches `10 in the upper portion of the lower cylinder 8.

A cylinder head is adapted to be clamped, at will, either to the upper portion of the lower cylinder 8 or to the upper portion of the upper cylinder 7, and to accomplish this,-

the said cylinder head 11 is provided with depending L-shaped lugs 12 that are engageable with L-shaped notches 13 formed in the upper portion of said upper cylinder 7 The lugs i2 on. the head 11 are duplicates of the lugs 9 on the cylinder 7 and the notches 13 inthe cylinder 7 are duplicatesof the notches 10 inthe cylinder 8., The cylindrical fiange of the v cylinder head 11 is of the same diameter asthe cylinders 7 and8, so that itfits freely around the eX- tremeupper end of the carton A. As shown, the cylinder head 11 is reinforced by ametal disc 111 soldered or otherwise rigidlysecured thereto and'.r provided with openings 15 that permit the escape of air in the filling of the carton and observation of the filling operation. Here it should be stated that the openings 15 are also in the web of the cylinder head proper. The cylinder head is provided with an axially projecting rigidly attached stem or handle 16 terminated in a cross bar 17.v l f When the cylinder head is removed, the carton is adapted to jbe inserted into the cylindrical casing made up either of the two cylinders 7 and 8 or of the cylinder 8 alone, and moved downward against a stop flange or shoulder 18 formed by a metallic collar 19 set into the lower end of the cylinder 8 and there secured by soldering, sweating, orA

otherwise. The interior diameter ofthe collar 19 is not less and may be slightly greater than the internal diameter ofthe carton A..

Said collar 19 is preferably shouldered and extended flush with the exterior of the cylinder 8. At its lower or projecting edge. the collar 19 is formed with serrations or teeth 20, several of which are slightly bentv outward and some of which are slightly bent inward, so that they are given a ,set much like the teeth of a saw. These teeth, under rotation of the casing, will cut an annular or cylindrical groove in a cake or mass of ice-cream that is slightly wider than the combined thickness of the casing and carton completely filled withA ice-cream. `While the ice cream acted uponby these teethwill not actually be forced out of the groove cut by the teeth, the cream acted upon by the teeth will, nevertheless, be softened up so that the cylindrical casing may be easily forced through the same. 1n fact, the cream thus loosened up seems to act more or less as a lubricant or, at any rate, such softened material can be readily displaced when the cylindrical casing is forced through the body of cream. The sharpness of the teeth 20 also makes it an easy matterto force the device into the ice-cream to fill the carton.

Figs. 1 and 2 show the device with the two Cil cylinders 7 YandS` interlocled'ancl`yvith the cylinder head interlocked to the cylinder 7 thereby adjusting the device to lioldalargesize'for quartfholding.carton. l/Vhen the dee vice-'Visto be usedto hold. aashort-carton, such as a pint-containing carton, the cylinder 7 is removed and the cylinder head. willthen, be.

directly interlocled to the cylinder 8. It is important to note that; in anylanld allof the arrangements, the external surface of the casingfandof the lcylinder head are Hush and present a smooth exterior surface.

Thev numeral 2l indicates a combined clamp-and scraping ring, being preferably formed from square wire bent to form a spring ring with outturned ends 22. rlhis ring 2l is of a size to quite freely engage the exterior of the metal'casing and,r normally, it may be helden t-he flange of the cylinder' head l1 by 1 springiclips 23 shown as applied to the latter. Should any ice-cream adhere to the exterior of the casing, it may be readily7 removed by forcing the ring 23 downwardwhile frictionally holding the same under light pressure produced by pressing together more or less the ends 22. Also, this split ring may be used to clamp and :hold either of-the cylinders or case sections 7 01'18, while connecting or disconnect-y ing the same. f

Attention is called to the factthat in Fig. 61; the ring-2l is shown-as of slightly smaller scale than in Figs. l and 2.

As is evident, when a carton has been filled andit's cylinder head removed, such filled carton-may be readily engaged by the fingers and removed from the casing. In practice, it has been foundthat the filling operation may be performed very rapidly and satisfactorily.

The device is herein designated as an icecream carton iiller, but, as is evident, it may be used for other or similar purposes.

What I claimis:

1. An ice-cream carton filler Comprising a plurality of detachably connected coincidenty cylindrical sections having interlocking joint-forming elements located within the cylindrical space common to the said sections.

2. An ice-cream carton fillery comprising a cylinder adapted to contain a carton and provided at its receiving end with serrations or'teeth'adapted to cut a cylindrical groove to receive the casing and carton therein c ontained, said casing atitsreceiving end having afstop limiting the `downward tmovement ofthe carton, and a handle-equipped head detach'ably applicable to tlie-upper'en'd'of said` casing, Vthe 'said casing'being made up of detachablyconnected sections. 3..An .icecream carton filler comprising a cylinder adapted to contain a carton and provide'd at itsreceiving end with serrations or teeth adapted to cut av cylindrical grooveVV to receive thef casingV and carton therein contained', said casingatuits receiv ing end'having 'a stop limiting the'downward -movement of the carton, and ahandleequipped head detachably applicable to Vthe upper end'ofsaid casing, saidcasi-ngbeing made up of sections, said sections and said head having interlocking elements -whereby the two sections may be detachably connected and the headdetachably connected to the upper section, or the upper section may be removed'and said head detachably connected to said lower case section.

4. Anfice-cream cartonller comprising a cylindrical-shell made up zoffc-ylindrical sections and a head', said sections havingintei-locking'engagement and* the saidhead having interlocking v engagement with either of said cylindrical sections.`

5. vAn ice-cream carton fil-ler 'comp-rising a cylindrical shell-made 'up of cylindrical sections and ahead, said sections having interlocking engagement and thesaid head having interlocking engagement with either of said cylindrical sections, one o-f'said cyli'ndrical sections Ahaving avcutting edge at its-'receiving end, also saidy sections lying within a common cylindrical space.

6. Anv ice-cream carton filler comprising a cylinderi adapted to -containa' carton and provided vat its receiving end with teeth and above the teeth-with an inwardly projected stop ledge for limiting the downward movement of the carton, the said teeth having a cutting width at least as great as the yradial thicknessV of said cylinder and its stop ledge, whereby said teeth will cut 'an annular groove wider than the combined thickness of said casing andthe carton therein contained. ,7. The struct-ure defined in claim 6 in which said teethfare beveled circumferentially in both directions from ltheir cutting poi-nts.
